From: Infection transmission and chronic disease models in the study of infection-associated cancers
Transmission models represented as flow diagrams. Some examples of alternative compartmental models for modelling infectious diseases. The total population is distributed into mutually exclusive epidemiological compartments. The models are defined by these compartments and the possible transitions between them. In the simplest models, there are two or three states: susceptible, infectious, and recovered. More complex models can also account for a latent infection, and carrier status. Finally, transmission and carcinogenic phases of the natural history of infection-related cancers can be combined into a single model.
